I am having trouble keeping it running and/or starting it. I went to the garage and it started right up no problems, cut the front yard, turned it off to let it sit in the shade since it was 100 degrees out. I got back on it after decluttering the back yard of toys, which was about 15-20 minutes, and it would turn over but would not fire. I let it sit over night in the garage and the next morning went out and it fired right up with no problem. I got about 30 minutes into cutting and it started to sputter, died, and I could not get it to started. It would turn over but would not fire. I checked the carb, it looked good but I cleaned it anyway. I replaced the oil, oil filter, spark plug, air filter, fuel filter, drained all the fuel and replaced it with new fuel. I got it to fire up and it ran for about 10 minutes and then died again. I can get it to turn over but it still will not fire. Any suggestions or am I S.O.L?

Hi,
You have described a fairly "classic" Ignition module failure. The first time was when you shut it off to pick up the toys; the heat of the engine rose and induced the failure. The second time is almost the perfect time span for a failure from start to failure.
Peace,

PS Give some engine numbers and I will give you a part number.
